I think you'll find that the Vit A from Milo is derived from vegetable sources rather than animal, in which case it is fine.

My OB in Darwin used to actually recommend Milo to his pg women, as it also contains good high levels of magnesium, which helps minimise leg cramps later on in pregnancy.

I had a fair amount of milo with my pregnancy with Olivia with no ill effects whatsoever.

Always check with your Dr, but I would say that Milo is perfectly OK............
